CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 10-2012-0097924, filed Sep. 4, 2012, which is hereby incorporated by reference in its entirety.

BACKGROUND

Embodiments relate to controlling a lighting device based on at least one of a received signal strength indication (RSSI) received from the lighting device, and a preset lighting mode.

A general lighting device may be controlled when a power switch and a lighting device are connected one to one and a desired switch is known.

Also, color temperature or/and brightness of each lighting device should be manually controlled based on a user's determination.

Further, when a user goes out or returns to home, the user has to turn off or on each lighting device, personally.

The above-mentioned control method, however, causes inconvenience in use since the user personally performs an action.

Meanwhile, as one of endeavors toward environment-friendly/low carbon energy and energy saving, social and national needs for an LED lighting have been sharply increased. However, in spite of efficiency and technical advantages of the LED lighting, the LED lighting has a realistic problem in that it is not widely used due to a high prices and a limitation in technical difference able to overcome the price issue compared to an existing lighting device.

BRIEF SUMMARY

Embodiments provide an effective control of a lighting device based on a received signal strength indication (RSSI) received from the lighting device.

Embodiments provide a control of brightness or/and color temperature of a lighting device to two or more levels according to RSSI.

For example, embodiments provide realizing an emotional control of lighting based on a user's taste by differently setting a color control signal, a color temperature signal, and a brightness signal of a lighting device according to RSSI at an Application Software of a smart phone that is one type of lighting control devices.

Also, when a user with a lighting control device goes into a place where a lighting device is installed, the lighting device is controlled to be automatically turned on, when the user approaches or moves away from the lighting device, the level of brightness/color temperature may be controlled to be increased or decreased, or when the user goes out the place, the lighting device is turned off, to thus enable the emotional control.

According to embodiments, the lighting device may be controlled such that the brightness level of the lighting device of an indoor room is automatically lowered when a user goes out, and is automatically elevated when the user enters the indoor room. For example, as the RSSI increases, the level of color temperature/brightness is gradually elevated (brightened), and as the RSSI decreases, the level of color temperature/brightness is gradually lowered (darkened).

According to embodiments, the lighting device may be controlled to be automatically turned off when a user goes out and to be automatically turned on when the user enters an indoor room according to the RSSI, and the lighting device may be set such that as the RSSI increases, the brightness level increases (is brightened), and as the RSSI decreases, the brightness level decreases (is darkened).

Thereafter, as illustrated in FIG. 14, the color temperature of 2,700K in the Relax mode is changed to 1,500K, and the brightness is changed from 700% to 50%. Thus, the RELAX Icon in the activated state is converted to an inactivated state.

FIG. 15 is a flow diagram showing that the respective lighting modes are expressed in UI pictures and are selected and controlled by a user's selection.

As shown in FIG. 15 and table 2, two or more lighting modes are set by at least one of the color temperature and brightness, and are then stored in the storage unit 204 of the lighting control device 101 and the storage unit 214 of the lighting device 111, respectively (S1501).

A lighting control mode is selected through the input unit 206 of the lighting control device (S1502).

The preset lighting mode is displayed on the UI picture, and the lighting device is controlled according to the lighting control information set as default values (S1503, S1504).

Thereafter, among the displayed lighting modes, the mode to be outputted is selected by the user, and the color temperature and brightness illustrated in FIGS. 11 to 14 according to the selected mode are outputted (S1505, S1506).

Meanwhile, in the state set and outputted as above, by moving the scroll bars or selecting another mode, the lighting control device may be operated with the changed lighting control information values (S1507, S1508, S1510, S1511).

As the lighting control information is changed, the activated Icon of the lighting control mode is converted to an inactivated state (S1509).

The change of the lighting control information will be possible by controlling the means (e.g., scroll bars, cursor, etc.) indicating the current states of the color temperature and brightness.

By moving the scroll bars or selecting another lighting mode in the above, the activated icon of the selected lighting mode is converted to an inactivated state, and the newly selected icon is activated.
